The two latter features can also be used sensibly if you wish to interrupt a current braking process
prematurely.
The constant braking distance does not work if the layout is operated in analogue DC mode.
4.6 Shunting speed
The shunting speed halves the speed. This facilitates particularly sensitive control of the shunting
process. Use function 3 (ex-works setting, can be altered in CV59) to enable and disable the
shunting speed. If the shunting speed is enabled, the constant braking distance is disabled. The
shunting speed is enabled as long as the function is active.
4.7 ABC = simple signal stop and slow approach
You can carry out a particularly simple signal stop using the ABC braking module. Depending on the
signal position, this module creates an asymmetric track voltage in the braking section in front of the
signal. The decoder reacts to this. Combined with the constant braking distance, precise on-the-
spot stopping in front of red signals is not a problem. Of course, passage in the opposite direction is
also possible. The signal indication "slow approach/caution" does not pose a problem; the
respective speed can be set in CV53.
You can operate all functions during the signal stop or slow approach – you can even reverse away
again from the red signal! These special ABC modules can be used to assemble a very simple
block section. Activate the ABC module by setting Bit 2 (1) in CV51.
The ABC feature is not active whenever the shunting speed is switched on or the delay is disabled.
4.8 Push-pull train control
A push-pull train control can be set if the ABC braking module is used. There are two different
options: push-pull operation with and without intermediate stops. The latter also takes slow-
approach sections into account.
